Cool vids. Thanks for posting.
Angel Huerta's vid really didn't show too much of his skills, I didn't think, but from a filmmaking standpoint (and I'm a film major, so these things interest me) it was really nicely done. Very slick. I liked it.
In the second vid, the dude clearly comes from a TMA background. Really nice movement and technique. His opponent looked mystified. I can see some reason for a comparison to Pettis.
Speaking of Pettis, interestingly enough, he comes from a TKD background and, perhaps more interestingly, was involved with a TKD organization that gets almost no respect. That is, the American Taekwondo Association. But he has clearly carried some of that training over into his MMA career.
